This PML cover fits the GM 9½" ring gear, 14 bolt rear differential. PML makes three different covers for the many GMC and Chevrolet trucks, vans and SUVs with this differential.
PML designed this cover specifically for vehicles needing clearance for pan hard and sway bars and still want the benefits of an aftermarket heavy duty cover. For example:
Vehicle configurations vary so always check your configuration and clearance before ordering.
If you do not have an H2, Trailblazer SS or SSR and wish to order this cover, you will need to contact us and let us know what bolt size you have. Please see the Bolt Information section on this page: GM straight fin cover. All the Hummer H2, Trailblazer SS, and SSR vehicles we have seen have metric M8–1.25x21mm stock bolts.
We have one of these covers on special: Special #224
Nissan Titan 2016 and newer: These trucks have a similar rear stock cover. See PML Products In Development.

Our thanks to Eugene (retired Marine) for sending us pictures of his installation and for his service to our country.
Installation on a 2007 Cadillac Escalade
Kirt installed this cover on his 2007 Cadillac Escalade 6.2L 2WD. He reported that the rear track bar needed to come off to get the cover on, but there is about 1/4 inch clearance when it is all back together. His Escalade uses the same bolts as the H2 (M8–1.25x21mm). Our thanks to Kirt for letting us know.
